Our People: 2024 Corporate Progress Report

Each year, we report on several indicators that show progress toward our “people” goals for an inclusive culture, a healthy workplace, and ample opportunities for leadership development and professional growth.

32% of Employees are Women

At 32%, we have a higher percentage of women on staff than is typical of our professions (see Society of Women Engineers). We continue to support our employee network group for women, Women@TT – now in its 11th year – and provide opportunities for women to advance in their careers. And 88% of women in the firm feel that Thornton Tomasetti is an inclusive place to work. This metric is based on self-reported employee records.

89% Retention of Female Employees

Our retention rate of 89% for 2024 remains high and has been trending upward for the past four years. During this time, we’ve added programs to strengthen retention at critical junctures in women’s careers. This metric is one indicator of a viable pipeline for the advancement of women into senior leadership positions.

38% of U.S. Employees Are People of Color

Thornton Tomasetti demonstrates commitment to a diverse workforce by fostering an inclusive culture and by supporting Mosaic, a growing employee network group focused on multicultural issues. In our survey, 86% of our people reported that they feel they can bring their full self to work. The metric is based on self-reported employee records from our U.S. offices; we do not collect this data outside the U.S.

80% of Employees Believe Their Development is Encouraged

In our annual employee survey, we asked the question, “Does someone at the firm encourage your development?” The answer for 80% of our employees was “yes.” Encouragement can come in many ways: informally from a colleague, from a supervisor or through our formal mentorship program. In 2024, we paired more employees with mentors than ever before, for a total of 423 matches. On a related note, 91% of our people feel comfortable asking for help from people at work whenever they need it.

14% of Employees have Ownership

Thornton Tomasetti is an employee-owned company, with owners providing input on the firm’s strategic direction. The program enables broad ownership opportunities for leaders across the firm (typically for employees who reach associate principal-level and higher) and supports a culture of entrepreneurship and business acumen. Although the percent of owners stays has remained constant, at 14 to 16%, our total number of owners has increased along with the firm’s growth.

19% of Owners are Women

Women in the AEC industry have typically been a minority in leadership positions, but that is changing. Because it’s tied to advancement, ownership is one indicator of leadership at our firm. The percent of women who are owners – in 2024 19% of owners are women – is gradually increasing as women move through the development pipeline into leadership roles.

3,238 Company-Paid Community Service Hours in 2024

This metric tracks total on-the-clock hours our employees spend in community-service activities each year. It includes time tracked through our Volunteer Days benefit and half the hours employees spent participating in the ACE Mentor Program. Hours contributed to Bridges to Prosperity are also included. We are meeting our goal of increasing paid-time service hours each year, with the largest jump following the pandemic, when in-person volunteerism was low.
